Title: The eye’s response to defocus and diffuse blur
Two common sources of blur are defocus (eg. due to lenses) and diffusers (eg. frosted glass). This thesis provided a comprehensive analysis of vision quality with various levels of diffuse and defocus blur. Diffuse blur leads to excessive eye growth in animals (known as form deprivation myopia), but the underlying mechanism is unknown. Short-term studies of eye length were conducted with humans wearing diffusers and defocus lenses to investigate if certain aspects of the visual image were critical for the control of growth. The level of vision loss was not responsible for the short-term eye length changes.
